Designing Web Apps for Performance

About this presentation

React makes it easy to build beautiful and responsive JavaScript applications. But moving rendering from server to client reveals new and unique performance challenges. Preloading data, minimizing round trips, and reducing JS overhead are some of the problems JavaScript developers face. Server and client execution are fundamentally different; each has distinct strengths and weaknesses. Building fast applications means designing systems that combine the strengths of both of these environments. We'll look at how Facebook is doing this with abstractions like GraphQL and Relay, the specific problems that each library solves, and how we can apply the same design principles to other performance problems.
